Abstract
The invention relates to an anti-corrosion treatment method of Nd-Fe-B ferrite. The method comprises the following steps: pretreating to ensure the clean and smooth external surface of Nd-Fe-B ferrite, namely degreasing Nd-Fe-B ferrite, performing bright dipping, rinsing, activating, rinsing again and the like; implanting an anti-corrosion material on the surface of Nd-Fe-B ferrite through ion implantation; and then forming a metal oxide layer or plating or anti-corrosion layer on the surface of Nd-Fe-B ferrite.
Description
Technical field
The invention belongs to the technical field of surface of magneticsubstance, refer to especially a kind of for neodymium iron boron ferrite rot-resistant treatment process.
Background technology
Neodymium iron boron ferrite has excellent magnetic property as rare earth permanent-magnetic material, and good mechanical workout characteristic and relative cheap price are widely used in fields such as automatization, computer, household electrical appliances, communications.But neodymium iron boron ferrite materials chemistry poor stability is easy to oxidation in environment for use, and under wet heat condition serious chemical corrosion can occur, and worsens magnetic property and affects work-ing life of magnet.
The main method that solves at present the neodymium iron boron ferrite etching problem is at magnet surface deposition one deck corrosion-resistant coating, main treatment process has the process of surface treatment such as electrochemical plating or electroless plating, but these two kinds of techniques all have obvious defective, be exactly to have in process of production a large amount of waste water to produce, and the high harm of the intractability of this class waste water is large.Power consumption is large when use electroplating, and is unfavorable for energy-conservationly, does not meet environmental protection and energy-conservation requirement.
Summary of the invention
The purpose of this invention is to provide the antiseptic novel method of a kind of new neodymium iron boron ferrite, the method does not have a large amount of sewage to produce in process of production, and it is little to compare power consumption with plating.
The present invention is achieved by the following technical solutions:
Neodymium iron boron ferrite rot-resistant treatment process, its step are at first to be pre-treatment, and neodymium iron boron ferrite is carried out oil removing, bright dipping, and rinsing, activation, the processing such as post rinse are with the outside surface cleaning that guarantees neodymium iron boron ferrite and smooth.
Next is to adopt ion implantation mode to inject anticorrosion material on the neodymium iron boron ferrite surface; Then form metal oxide layer or coating or preservative coat on the neodymium iron boron ferrite surface.
Described anticorrosion material is metallic nickel.
Described ion implantation be the 42-45KeV magnitude with energy;
Described altogether network layer thickness is 15-40nm.
Described injection rate is 25mg/cm
2-40mg/cm
2
The beneficial effect that technical solution of the present invention is compared with prior art is:
By this treatment process, inner by the surperficial body that anticorrosive agent is directly penetrated into neodymium iron boron ferrite, preservative coat can not come off, add other protection against corrosion mode, obviously improve the corrosion resistance nature of neodymium iron boron ferrite, and little in the production process environmental pollution, meet the national energy-saving environmental requirement.
Embodiment
The following specifically describes embodiments of the present invention.
At first get the base substrate of neodymium iron boron ferrite, also can choose as required the neodymium iron boron ferrite material of other model or shape, base substrate to neodymium iron boron ferrite carries out pre-treatment, neodymium iron boron ferrite is carried out oil removing, bright dipping, rinsing, activation, the processing such as post rinse are with the outside surface cleaning that guarantees neodymium iron boron ferrite and smooth.
Next is to adopt ion implantation mode to inject anticorrosion material on the neodymium iron boron ferrite surface; Then form metal oxide layer or coating or preservative coat on the neodymium iron boron ferrite surface.
Described anticorrosion material is metallic nickel.
Described ion implantation be the 42-45KeV magnitude with energy..
Described altogether network layer thickness is 15-40nm.
Described injection rate is 25mg/cm
2-40mg/cm
2
Of the present invention described ion implantation be the 42-45KeV magnitude with energy; Concrete selecting of Implantation Energy is to select according to the purposes of material or definite injection thickness, the thickness that injects in the present invention amorphous substance is 15-40nm, select the thickness that injects low when abominable or calling hierarchy is not high when the environment of materials'use, the also corresponding reduction of energy of therefore injecting usefulness; Abominable when the environment of materials'use, the thickness of injection is thick, the also corresponding raising of energy of therefore injecting.Employed Implantation Energy, injection thickness and unit consumption all are not quantitatively final in the present invention, and just relatively good data can be adjusted according to actual needs, may reach 100KeV magnitude or even 120KeV magnitude such as Implantation Energy; Inject thickness and also may reach 75nm; Unit injects consumption also may reach 80mg/cm
2But the desired minimum data of this patent is master data, if be lower than minimum data then Corrosion Protection can't reach best.
Above specific embodiment only can be as reference of the present invention rather than limitation of the present invention.
